Earlier quoted context omitted.
That would also be the notion behind a system of awards for copyable works, so I'm not sure what your point is.
No, the award system that's being discussed leaves applicants with no certainty that they'll actually be compensated for disclosing. That's not the case with the patent system; subject to modifications, competent patent applicants are virtually certain to get a patent 7 years after applying.
But, there's no guarantee of reward. Far from it, you've only got a letter of marque, not the ship or crew to profit from it with.
In a reward system it'd be totally different. No applications, no licenses, just instant wide disclosure. If you don't tell people they can't use it and you won't get rewarded.
And you could just document and teach someone else's invention and get rewards that way, in proportion to the value of the accessibility you added.
